Abstract
The invention discloses lubricating grease special for blast-furnace equipment and a preparation method thereof, and belongs to the technical field of lubricating grease. According to the technical scheme, the lubricating grease special for the blast-furnace equipment is prepared from, by weight, 54% of base oil A, 30.8% of base oil B, 2.2% of diaminocyclohexane, 1.9% of aminoxylene, 7.8% of 2,2'-dimethyldiphenylmethane-3,3',5,5'-tetraisocyanate, 0.1% of T322 and 3.2% of T361A, wherein the base oil A is mineral oil or ester oil, and the base oil B is 150<#> mechanical white oil. The invention further discloses the preparation method of the lubricating grease special for the blast-furnace equipment. The lubricating grease special for the blast-furnace equipment can be used when the environment temperature is 200 DEG C, the high-temperature resistant property is achieved, the lubricating grease further has good pumpability, the lubricating grease can be pumped into a farther-distance bearing, and concentrated grease supply can be achieved; in addition, the lubricating grease does not blacken and coke in the bearing, and the lubricating grease does not coke even through the lubricating grease is kept in the bearing for a long time.
Description
Technical field
The invention belongs to technical field of lubricating grease, be specifically related to a kind of blast-furnace equipment special grease and preparation method thereof.
Background technology
Lubricating grease in the market more tends to specialized, and according to the feature using parts, research and development and production specific adaptation are in the lubricating grease using member characteristic.Lubricating grease kind on market is a lot, does not have the lubricating grease that iron-smelting blast furnace is special at present.Some producers use Special high-temperature lubricating grease as blast furnace lubricating grease, and some producers use lithium soap grease as blast furnace lubricating grease etc.These lubricating grease are not that professional is not very strong specially for the lubricating grease that the feature of blast-furnace equipment is produced.Although Special high-temperature lubricating grease can adapt to the hot properties of blast furnace very well, price is too high, and in order to cost keeping, this lubricating grease can not at iron work popularity.Lithium soap grease is lubricating grease commonplace on market, price transparent, and the over-all properties of lithium soap grease is also fine, but the applied temps of lithium soap grease can not reach the requirement of blast-furnace equipment.Lithium soap grease and Special high-temperature lubricating grease also have a maximum shortcoming to be grown duration of service not have timely grease up, and the easily coking within the bearing of these two kinds of lubricating grease, will form impurity after coking, can produce very large harm to bearing inside bearing.
In blast-furnace equipment, the equipment of special operation condition mainly contains, apparatus for feeding, and they are above blast furnace, and envrionment temperature is higher, and location comparison is high, so take to concentrate for fat, namely pumping, does not need workman to get on operation.The equipment of molten iron discharging, this local temperature is higher, and workman can not near work, and grease up is also pumping.Take out furnace gas system and enter hot-air system.Blast furnace can produce a large amount of gas in the process of melting iron, and these gases are harmful, and therefore must release in airtight space, furnace gas temperature is very high, so the bearing of induced draft fan must can bear higher temperature and good sealing property.Furnace gas is through purification, heating, again by the stove that is again fed into below blast furnace, because these air temperatures are all very high, therefore the necessary high temperature resistant and good seal of the bearing of their induced draught system, must be also that pumping supplies fat, for the special operation condition of blast furnace, be necessary to design a kind of lubricating grease used specially on blast-furnace equipment.
Summary of the invention
The technical problem that the present invention solves there is provided a kind ofly has blast-furnace equipment special grease of resistance to elevated temperatures, good seal performance and good pump-conveying property and preparation method thereof.
The present invention adopts following technical scheme for solving the problems of the technologies described above, a kind of blast-furnace equipment special grease, it is characterized in that being prepared from by the raw material of following weight percent proportioning: base oil A54%, base oil B30.8%, ring diamines 2.2%, xylidene(s) 1.9%, tetraisocyanate 7.8%, T3220.1% and T361A3.2%, wherein base oil A is mineral oil or Esters oil, and base oil B is 150
#machinery white oil.
The preparation method of blast-furnace equipment special grease of the present invention, is characterized in that concrete steps are: base oil A and base oil B pumps in saponification still with after 120 object filter screen filtration by (1) respectively; (2) add xylidene(s) when saponification still being heated to 80 DEG C and be uniformly mixed, continuing add ring diamines when being heated to 90 DEG C and be uniformly mixed, continuing add tetraisocyanate when being heated to 100 DEG C and be uniformly mixed; (3) stop heating when being continued to be heated to 130 DEG C by saponification still, then material is poured into and be in harmonious proportion in still and keep 1h in 130 DEG C, stir 5min every 20min during maintenance and arrange process to complete molecule; (4) add T322 and T361A when the temperature of mediation still is reduced to 100 DEG C, be uniformly mixed rear startup recycle pump, obtained blast-furnace equipment special grease after clarifixator circulation and shearing.
Lubricating grease of the present invention can use when envrionment temperature 200 DEG C, there is high-temperature stability, this lubricating grease also has good pumping, it can by pump delivery in longer-distance bearing, can concentrate for fat, this lubricating grease can not blackening coking in bearing in addition, though the lubricating grease time in bearing grown lubricating grease also can not coking.
Embodiment
Be described in further details foregoing of the present invention by the following examples, but this should be interpreted as that the scope of the above-mentioned theme of the present invention is only limitted to following embodiment, all technology realized based on foregoing of the present invention all belong to scope of the present invention.
Embodiment 1
(1) by 540 kilograms of mineral oil and 308 kilogram 150
#machinery white oil pumps in saponification still with after 120 object filter screen filtration respectively; (2) add 19 kilograms of xylidene(s)s when saponification still being heated to 80 DEG C and be uniformly mixed, continue add 22 kilograms of ring diamines when being heated to 90 DEG C and be uniformly mixed, continue add 78 kilograms of tetraisocyanates when being heated to 100 DEG C and be uniformly mixed; (3) stop heating when being continued to be heated to 130 DEG C by saponification still, then material is poured into and be in harmonious proportion in still and keep 1h in 130 DEG C, stir 5min every 20min during maintenance and arrange process to complete molecule; (4) add 1 kilogram of T322 and 32 kilogram T361A when the temperature of mediation still is reduced to 100 DEG C, be uniformly mixed rear startup recycle pump, obtain blast-furnace equipment special grease through clarifixator circulation with after shearing 1h.
